HAY-STACKER.

Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed July l4, 1905. Serial No. 269,583.

To aZZ whom it may concern/.

Be it known that we, MAURIon KANE, residing at Chicago, in the county of Cook and State of Illinois, and ALBERT Garnvns, residing at Springfield, in the county of Clark and State of Ohio, citizens of the United States, have invented certain new and useful Improvements in Hay-Stackers, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

Our invention relates to hay-stackers belonging to that class wherein the hay is elevated from a lower to a higher plane by means of a fork pivotally connected to one arm of a lever or boom mounted upon a rotatable mast and which is elevated by means of power operative to raise the fork.

It consists in an improved construction designed to lessen the number of parts and in providing a simple and strong mechanism for the desired purpose, the object being to provide a mechanism that will be easily manipulated, positive in its action, and more compact than those heretofore constructed. We attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a hay-stacker embodying our invention. Fig. 2 is a detail of a part of the fork-elevating lever, and Figs 3 and 4 are details of parts of the elevating mechanism.

Similar characters refer to similar parts throughout the several views.

1 represents a bed-frame constructed in any approved form upon which is rotatably mounted a short standard or mast 2, which is supported laterally by means of braces secured at their upper ends to a ring 3, encircling the mast and forming a bearing therefor, and at their lower ends to the bed-frame in the common manner. Pivotally mounted at the upper end of the rotatable standard is a lever comprising the rearwardly-extending parallel arms 4 and 5 and the forwardlydi' verging arms 6 and 7, having their rear ends secured to the arms 4 and 5 beyond their pivotal connection 7 with the standard by means of bolts 7 and connected with said arms at the opposite side of their pivotal connection by means of a bridge-piece 8, that forms a strut for truss-rods 8, secured near opposite ends of said lever to the several arms. Pivotally mounted at the outer ends of the diverging arms is a fork 9 of common form, having a standard 10 secured to its rear end, to the upper end of which is secured one end of a flexible member 11, that passes inward and below a sheave 12, supported by the arms 6 and 7, and over a sheave 13, mounted on the bridge-piece 8, and over a third sheave 14, mounted between the bars 4 and 5 and having its opposite end secured to an adjustable link 15, pivotally connected with a locking-lever 16, that is pivotally mounted on an arm comprising the bars 17 and 18, secured to the standard 2 and supported by braces 19 and 20, secured at opposite ends to the standard and bars. Pivotally mounted at the outer end of the arm, between the bars upon a horizontal pivot, is a sweep-lever 21, operative to turn the mast in its bearings.

The lever 16 when depressed engages with a projection 22 on the bar 17 in a manner to lock the fork in operative position, and to release the lever from engagement therewith there is provided a cam-shaped strap 23, that is secured to the inner end of the sweep-lever 21 and adapted to move the lever 16 laterally away from the projection when the outer end of said sweep-lever is raised, as shown and claimed in application filed May 17, 1905, and having Serial No. 260,750.

The hoisting mechanism comprises a cable 24, to the end of which the power is applied. The cable passes inward and around a sheave 25, flexibly connected with the lower end of the standard 2, and then outward and under a sheave mounted between the bars 17 and 18. For convenience of construction the sheave is j ournaled 011 a bolt that secures the braces 19 and 20 and the bars together, and the head or nut of the bolt forms the projection 22, with which the lever 16 engages, as previously described. The cable then extends upward and over a sheave journaled on a bolt that connects the rear ends of the arms 4 and 5, and then downward to a separate sheave j ournaled between the bars 17 18, coaxially with the second-mentioned sheave, and again upward and over another sheave journaled between the arms 4 and 5, coaxially with the third-mentioned sheave, and then downward and secured, by means of the link 26, to a part of the swinging frame connected with the mast. There may be as many loose sheaves at the ends of the arms 4 and 5 and between the arms 17 and 18 as desired in order to multiply the 'efiective power.

What we claim as our invention, and desire to secure by Letters Patent, is

1. In a hay-stacker, the combination of a bed-frame, a standard rotatably mounted on said frame, a fork, a lever pivotally mounted near its middle portion at the upper end of said standard, said lever comprising parallel bars pivotally supported near their inner ends upon opposite sides of said standard, bars secured at their inner ends to said parallel bars near their pivotal connection with said standard and diverging outward and having said fork pivotally connected with their outer ends, and a bridge-piece connecting the inner finds of said parallel bars with said diverging ars.

2. In a hay-stacker, the combination of a bed-frame, a standard rotatably mounted on said frame, a fork, alever pivotally mounted near its middle portion at the upper end of said standard, said lever comprising parallel bars pivotally supported near their inner ends upon opposite sides of said standard, bars secured at their inner ends to said parallel bars near their pivotal connectionwith said standard and diverging outward and having said end to said standard below the pivotal con-.

nection therewith of said lever, and flexible means connected at one end with said fork and adapted to control its pivotal movement and having its opposite end connected with said arm, said flexible means being guided by sheaves mounted upon said lever alone.

In witness whereof We hereto affix our signatures in presence of two witneses.
